Magic Links for Reviews

When the Magic Link function is enabled and you change the employer contact on the review then Onefile automatically changes any unsigned reviews to the new employer, this is going to cause problems with audit as the reviews will have the incorrect employer attached to them, in an ideal world you would say all previous reviews should be singed before changing the employer but that is never going to happen when you have hundreds of learners, they will never be 100% signed, Is there a way that

when you have the magic link function enabled and you change the employer that it only changes the employer going forward and  does not alter any previous reviews as this is leaving us wide open to problems at audit.
